Abundance of major taxonomic groups of invertebrates (arthropods and gastropods) collected with pitfall traps at four sites near Toolik Field Station Arctic LTER, Alaska in the summer of 2010.

Invertebrates (spiders, insects and slugs) were collected weekly using pitfall traps at four sites near the Arctic LTER at Toolik Field Station, Alaska. Traps were placed along transects in shrub (shrub-dominant) and open (tussock-dominant) tundra sites. Pitfall traps were placed for 48-hour intervals once per week from early June until mid-July 2010. Collected invertebrates were counted and identified to class (all invertebrates), order or family (for some of the most common families collected).

本研究于美国阿拉斯加州图利克野外站（Toolik Field Station）周边的4个北极长期生态研究（Long Term Ecological Research, LTER）样地内，采用地面陷阱诱捕器（pitfall trap）每周采集无脊椎动物（蜘蛛、昆虫及蛞蝓）。陷阱沿样带布设于灌丛（以灌丛为优势种）与开阔薹草丘苔原（以薹草丘为优势种）两类样地中。2010年6月初至7月中旬期间，每周布设一次诱捕器，每次放置时长为48小时。采集得到的无脊椎动物将被计数并完成分类鉴定：所有个体均鉴定至纲级，部分常见采集类群可进一步鉴定至目级或科级。
